there is one event that allows you to rectify where you stand when it comes to nameless (progress the orc questline) but as far as the original choice goes you're not allowed to change that
Yup, kinda figured that out, it's been a while since I played, and bad on me for not reading a guide on this fully before making the choice. I tend to test out choices at times, out of curiosity, and I shoulda made the correct choice before testing out anything else. (Used to the regular "Saves are important and we don't change that" kind of games o. o I suppose) \ o. o / it is a cool feature to have, but I would still recommend adding something that would allow a player to disable or change somewhere. (Especially as it is added so LATE in the game, so starting over is not exactly an option)
